Conservative activist, author, and blogging pioneer Andrew Breitbart, 43, collapsed and died of an apparent heart attack while walking outside his Los Angeles home

Breitbart cut his web teeth by helping Arriana Huffington launch HuffingtonPost.com before moving on to Matt Drudge’s DrudgeReport.com, then finally creating some of the more influential websites in conservative activism, including BigGovernment.com, BigHollywood.com, and BigJournalism.com.

Breitbart’s genius was his fearlessness. He stood up to ACORN with video stings featuring James O’Keefe and Hanna Giles pretending to be a pimp and a hooker entering ACORN offices to request, and often recieve, assistance. He famously re-tweeted insults lashed at him by his adversaries, proving that he knew “what they were really about.” He ignored those that said he was crazy and went about revealing the truth by letting his enemies’ own words indict them.

because of the suspicious nature of His death there will always be speculations as to who killed this courageous man.
